However, there has no standard method of selecting suitable packing materials after the operation to relieve pain in patients and achieve the ideal hemostatic effect. We compared the postoperative complications and treatment effects of two different packing materials in patients with pituitary adenomas. Objective: To investigate the advantages and disadvantages of using a catheter balloon and iodoform gauze for hemostasis in patients undergoing pituitary tumor resection by neuroendoscopic transsphenoidal approach. Materials and Methods: We retrospectively analyzed these data of 48 cases treated with pituitary adenoma resection by the single nasal approach from January 2018 to October 2019 in Sun Yat-sen University Cancer Center. According to the type of sphenoid sinus packing material used, these patients were divided into balloon tamponade oppression group (24 cases) and tela iodoformum oppression group (24 cases), respectively. The balloon tamponade oppression group received catheter balloon tamponade oppression hemostasis, and the tela iodoformum oppression group underwent tela iodoformum oppression hemostasis. The outcomes and complications were compared between the two groups in which two kinds of sphenoid sinus packing materials were used for hemostasis after tumor resection by transnasal endoscopic approach. For the catheter balloon compression hemostasis method, on account of the plasticity of the balloon, the volume of water in the balloon can be adjusted according to the size of the patient’s own sphenoid cavity. The amount of bleeding and several complications in terms of discomfort during placement and removal of the packing material, rebleeding after removal of the packing, cerebrospinal fluid rhinorrhea and electrolyte disturbance are compared between the two groups. Results: 48 patients were enrolled. The two groups’ data of patients were similar in age structure, sex ratio, tumor size at baseline and so on. No complications, such as abscess formation, were found in both groups. The success rate in the compression with catheter balloon group was 100% (24 of 24 patients); and in the iodoform gauze group 83.33% (20 of 24 patients). A catheter balloon was more successful in stopping bleeding at early stage than iodoform gauze. There were no statistically significant differences in the hospitalization stay time, operating day to discharge day and tampon indwelling time (P > 0.05). There were also no significant differences in pairwise comparison between the catheter balloon group and iodoform gauze groups in the incidence of cerebrospinal fluid rhinorrhea or electrolyte disturbance between the two groups (P > 0.05).

Multifactorial risk factors including environmental, nutritional and genetic factors may affect the frequency, risks, and genetic features of PD in different geographic and ethnic regions. Background: Our aim was to investigate the sociodemographic and disease characteristics, cognitive performances of patients with PD in Nusaybin, a southeastern city, and Hendek a northwestern city which have different geographical-cultural status, and to investigate the possible effects of regional differences on disease characteristics. Method: This retrospective study includes the data of patients with the diagnosis of PD who presented to outpatient Neurology clinics of Hendek State Hospital which is a city in the northwestern region of Turkey between April 2017 and June 2018 and patients who presented to the outpatient Neurology clinics of Nusaybin State Hospital, which is a city in the southeastern region of Turkey between October 2015 and January 2017. SPSS.23c (Statistical package for Windows) database was used for statistical analysis. Results: Our study included 114 cases with Parkinson’s disease in Hendek and 96 cases in Nusaybin.The majority of patients had idiopathic PD (IPD) in both provinces (96.9% in Hendek, and 92.1% in Nusaybin). Educational status of female patients was significantly lower in Nusaybin when compared with Hendek (9.3% and 63.3%, respectively). Family history for IPD was significantly higher in Hendek than Nusaybin (31.7% and 9.9%, respectively). There was a positive correlation between educational status and cognitive performances of the patients in both groups. Negative correlation was found between standardized mini mental test (s-mmt) scores and stage, severity of IPD in both groups. Conclusion: The socio-cultural status of our country decreases by going from west to east. Thus knowledge about PD, accessibility to the hospitals and health centers with the opportunity to get optimum treatments may show variabilities in between the regions. We believe that our study provides a comparison of patients with PD in two different regions of our country with different geographic, genetic characteristics, and development levels.","PeriodicalId":19381,"journal":{"name":"Neuroscience and Medicine","volume":"53 1","pages":"63-73"},"PeriodicalIF":0.0,"publicationDate":"2020-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74050771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to assess an association between the NLR, and clinical characteristics and one-month outcome in acute ischemic stroke (AIS). Subjects and Methods: This case-control observational prospective study included 75 patients admitted to stroke unit of Ain Shams University hospitals with AIS, sub grouped into 3 equal groups according to subtype of AIS, in addition to 25 healthy individuals. The demographic characteristics of the patients, complete blood picture test results at presentation, National Institutes of Health Stroke Scale (NIHSS) scores and modified Rankin Scale (mRS) scores were recorded. The clinical outcome was assessed by the NIHSS and mRS scores after one month. Results: The total leucocyte count was significantly higher in large artery atherosclerosis (P = 0.004) and cardioembolic (P = 0.020) stroke groups, unlike lacunar stroke group (P = 0.082), when compared to controls. The neutrophils count was higher (P < 0.001) and the lymphocyte count was lower (P < 0.001) among all the stroke groups compared to the control group. The NLR was higher among all the stroke groups compared to the control group (P < 0.001). The NLR at cutoff value more than 1.34 had predicted stroke with a sensitivity of 89.33% and specificity of 72% and accuracy reached 88.6%.
